Noise measurements in RAW format are indicative of pixel performance, but the viewing conditions of the image must also be taken into account. To compare prints on a given format of cameras with different resolutions, it is more suitable to compute the equivalent SNR of a camera with a given reference resolution. For equal, normalized SNR, a high-resolution camera is still better than a low-resolution camera. While it is always possible to simulate a low-resolution camera using a higher resolution camera (since downsampling is easy), it is not possible to simulate a high-resolution camera using a lower-resolution camera other than by interpolating or inventing data.

To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.

On DxOMark, we evaluate and rank many types of digital cameras with image sensors that vary widely in pixel count, pixel size, and digital signal processing. To ensure that sensor performance comparisons between cameras are fair, it is very important both to test under identical shooting conditions and to take viewing conditions into account.
